MOBILE, Alabama -- BP has announced the sale of some of its oil and gas assets in the Gulf of Mexico along with an investment of $4 billion in the area over the next 10 years, according to a story at Sky News.

Plains Exploration purchased the assets for more than $5.5 billion. Those assets do not include the Deepwater Horizon site, the story said. The largest oil spill in U.S. history occurred at the site when an explosion destroyed the drilling rig and killed 11 people in April of 2010.
